Husqvarna Lawn mower not self propelling
If your Husqvarna lawn mower is not self-propelling, the problem is usually in the drive system, not the engine. The most common cause is a worn or broken V-belt, since the V-belt turns the drive pulley and helps power the wheels. Next, check the drive pulley itself. If it is worn or damaged, the transmission may not engage the wheel assembly. After that, inspect the wheel assembly gears. When those gears wear down, the transmission drive gear can no longer turn the wheels, which is a common reason a self-propelled mower is not pulling. If the pulley is spinning but the wheels still do not move, the transmission or transmission assembly is likely bad and will need to be replaced. A broken or misadjusted traction control cable is less common, but it can also keep the mower from moving under its own power. For the right Husqvarna replacement part, enter your model number on RepairClinic.com to match the exact V-belt, drive pulley, wheel assembly, transmission, or traction control cable for your mower.
01 - Husqvarna Lawn Mower V-Belt
The V-belt rotates the drive pulleys to drive the lawn mower wheels. If the V-belt is worn out or broken, the lawn mower wheels won’t turn. Inspect the V-belt for damage. If the V-belt is defective, replace it.

02 - Husqvarna Lawn Mower Drive Pulley
The drive pulley connects to the engine crankshaft. If the drive pulley is worn out or broken, the transmission won’t be able to engage the wheel assembly. Inspect the drive pulley for damage. If the drive pulley is defective, replace it.
Top Solution
03 - Husqvarna Lawn Mower Wheel Assembly
The wheel assembly has a set of gears which engage with the transmission drive gear. If the gears are worn out, the transmission won’t be able to engage the wheel assembly. If the gears are worn out, replace the wheel assembly.
Top Solution
04 - Husqvarna Lawn Mower Transmission
The transmission is powered by the drive belt, and the drive belt connects to the engine crankshaft. When the drive belt powers the transmission, the lawn mower wheels turn. To determine if the transmission is defective, observe the transmission while the lawn mower is running. If the transmission pulley is spinning, but the lawn mower wheels don’t turn, this indicates that the transmission is defective. The transmission is not repairable—if the transmission is defective, you must replace it.
Highly Likely
05 - Husqvarna Lawn Mower Transmission Assembly
The transmission is powered by the drive belt, and the drive belt connects to the engine crankshaft. When the drive belt powers the transmission, the lawn mower wheels turn. To determine if the transmission is defective, check the transmission while the lawn mower is running. If the transmission pulley is spinning, but the lawn mower wheels don’t turn, this indicates that the transmission is defective. The transmission is not repairable—if the transmission is defective, you must replace it.
Highly Likely
06 - Husqvarna Lawn Mower Traction Control Cable
The traction control cable might be broken or misadjusted. Check the traction control cable to determine if it moves freely. If the control cable does not move freely, try squirting a small amount of oil into the end of the cable to lubricate it. If lubricating the traction control cable is not effective, replace it.
